Issue with tesdisk and large files (>3gb)

#1 Post by bobsage »

There seems to be an issue with copying files over or around 3gb for me. I am copying from a failing HD to a new one. For some reason, when testdisk attempts to copy this files, it will go through the whole copy process, then as soon as it's finished, delete the file it just copied, then begin copying the file again. Pretty much stopping the whole file copy operation while it's in this loop. Most of these files are .mp4s

Is there possibly a way to alleviate this? I am using the system rescue cd with testdisk on it if that makes a difference.

Which version of TestDisk are you using ?
Example:

Code: Select all

testdisk -version
TestDisk 7.1-WIP, Data Recovery Utility, August 2016

Version: 7.1-WIP
Compiler: GCC 6.2
ext2fs lib: 1.43.1, ntfs lib: libntfs-3g, reiserfs lib: 0.3.1-rc8, ewf lib: 20140608, curses lib: ncurses 6.0
OS: Linux, kernel 4.8.8-300.fc25.x86_64 (#1 SMP Tue Nov 15 18:10:06 UTC 2016) x86_64
Are you copying the files to a FAT32 filesystem ?

The version that comes on the recovery CD is TestDisk 7.0, April 2015.

I believe I am copying to an NTFS filesystem.

I noticed something else odd with these larger files. When i'm navigating looking for the files I want to transfer. If its a larger file. It will show the file, and the file size on the left of it. Then underneath it, it will repeat the same file name maybe 6-10 times and each of these files has 0 for the file size.

I'm thinking what's happening is it's actually re-copying the file every time it goes over those other lines. So copying a 3.5gb file 8 times in a row makes it seem like its stuck on that file.

Latest 7.1 also shows multiple of the same files listed.

Any other ideas? I copied an example from someone else's post. It seems there is a bunch of "phantom" duplicates which testdisk attempts to recover after the initial file recovery, causing the same file to be recovered multiple times, considerably slowing down the recovery process.
